Doty did not return messages Wednesday. The district released a statement that said he will lead Education Direction and spend more time with his family.
Doty began guiding the new district's launch in August 2008, as it broke away from the Jordan School District following a controversial public vote in 2007. He oversaw the education of about 33,000 students from neighborhoods spanning upscale Cottonwood Heights, Sandy and Draper to the ski town of Alta and Midvale, home of many of Utah's immigrants.
During his tenure, he spearheaded a successful $250 million bond campaign to replace aging schools and the realignment of school boundaries. He implemented Utah's first "college ready" high school diplomas and scrapped with state education officials over the selection of assessment tests.
Several of Doty's supporters said Wednesday that he leaves the district in good shape, even if his leadership style was criticized at times.
"He had a strong personality," said Betty Shaw, Canyons PTA director. "He always supported us, so we had a good relationship."
Last year, some parents in the district questioned Doty's performance and an online petition was signed by hundreds.
Chad Iverson, who is now a member of the Canyons Board of Education, called for an independent investigation of misconduct allegations against Doty. Iverson, who did not return a phone call Wednesday, had claimed former district employees complained Doty used bullying and intimidation to maintain control.
Doty responded that he is prohibited by district policy from commenting on specific personnel issues, including those that involve him.
The board backed Doty and approved a raise that moved his base salary from $175,000 to $185,000. He also received a $25,000 one-time bonus because he had received no raises during the first four years of his contract.
Ross Rogers, president of the Canyons Education Association, which represents 1,600 teachers, said Doty has "ruffled feathers" with his hands-on style, but added that was to be expected when steering a new district. Rogers praised Doty for his restructuring of middle school grades in the fall, sixth-graders will move to middle schools, while ninth-graders will move to high schools.
Doty, 46, has been a prolific social-media user who aimed to sell and strengthen his young district.
"I think using these social-media tools is a way to communicate with people where they are," Doty said in a 2011 interview. "It's not waiting for them to come to you, it's taking the information to them."
Officials said Doty has prioritized visiting each of the district's schools and breaking down walls between parents, teachers and what he termed the "nebulous office of the superintendent."
He organized several "Ski and Shred With the Superintendent" events at Brighton Ski Resort and once took a group of students and parents to attend a speech by Facebook founder Mark Zuckerberg at Brigham Young University. Faculty members have said he is the most hands-on administrator they have ever encountered.
On Twitter, Doty has written about his love for the sports teams at BYU and Stanford, the schools from which he received his four degrees. His messages are often lighthearted and personal, but he also notes topical issues in education.
The school board will meet in the next two weeks to decide how to proceed with hiring a new superintendent. Board member Horiuchi said a committee will begin the search for the next district leader.
Board President Sherril Taylor, who did not return an email seeking comment, thanked Doty for his service, according to a statement from the district.
"To take this district from (a startup) to where it is now is nothing short of miraculous. We are thankful for that," Taylor said. "We thank your family for sharing you with us to get us where we are."
